Debugging and Programming Concepts Quiz

What is a breakpoint in debugging?

• A designated line in the code where execution is paused to inspect values and behavior

• A syntax error in the program

• A function that terminates execution

• A method for preventing bugs

Why is logging useful in debugging?

• It records events, errors, and outputs to help diagnose issues without stopping program execution

• It prevents compilation errors

• It replaces all loops

• It automatically fixes syntax errors

What is the purpose of a firewall?

• To monitor and control incoming and outgoing network traffic based on security rules

• To delete viruses from computers

• To store data permanently

• To slow down internet speeds

What is the main advantage of using a hash function in password storage?

• Hashing converts a password into a fixed-length, irreversible value, making it more secure against attacks

• Hashing stores passwords as plain text

• Hashing always produces different outputs for the same input

• Hashing prevents memory leaks

What is a higher-order function in programming?

• A function that takes one or more functions as arguments or returns a function as its result

• A function that runs in the background

• A function that can only be used once

• A function that never returns a value

What is a closure in JavaScript?

• A function that retains access to variables from its outer scope even after the outer function has finished executing

• A function that deletes variables

• A function that runs only once

• A method for debugging

What is double buffering in graphics programming?

• A technique where rendering is done in an off-screen buffer and then swapped with the visible buffer to prevent flickering

• A method for increasing frame rates

• A way to reduce memory usage

• A function that changes colors dynamically

How does collision detection work in a 2D game?

• It checks for overlapping bounding boxes, pixel data, or mathematical intersections between objects

• It automatically moves objects apart

• It prevents sprites from moving

• It disables physics calculations

In Boolean logic, what does De Morgan's Theorem state?

• It explains how loops function in programming

• It states that the negation of a conjunction is equivalent to the disjunction of the negations, and vice versa

• It converts all AND operations into OR operations

• It eliminates the need for conditionals in logic

What is the difference between == and === in JavaScript?

• === checks both value and type, while == only checks value and allows type conversion

• They are completely identical in function

• === is only used in Python

• == is faster than === in all cases
